TPM on dash question - tire pressure shows dashes only

[2025 Big Red]

When I start Big Red, the tire pressure display for the 4 tires and spare pops up. However, it’s just dashes.
Doesn’t display the pressure. Is there a setting I need to reset?

Not all trims show spare pressure, FYI.

sensors need to move before they transmit

I guess I didn’t ask question correctly. I get a dash display showing all five tires but no pressure is displayed. Is there a setting I need to change so it will display tire pressure. Yes, I can see tire pressure on app..

If the vehicle engine is started the pressures will appear after a couple of minutes the vehicle doesn't have to move
If you need to add air it takes a couple of minutes to display the new pressure
Good idea check tires with a pressure guage and compare to what the tpms displays
I have found they read about 1 psi lower than guaged pressure

Odd that you are seeing psi on app but not dash
Maybe looking at wrong set? Try switching sets and driving for a while.
To swap between sets: Settings -> Vehicle Settings -> TPWS Setting -> Tire Set Switching -> Register Valve/ID. Select the Set: Use the meter control switches to select the set that corresponds to the wheels currently on the vehicle ("Tire Set 1" or "Tire Set 2") and select OK.
The change takes a short time driving to show up on the TPMS power measurements on the dash. Note the difference: "register new valve/ID" vs "register valve/ID."
Not sure this is your issue but maybe??

yes no need to drive when it is all working and registered

but when there is a fault, system needs a full reset (change wheel)
you do need to drive around after that (typically) so system can register
the 'closest sensors' and sort them out from other radio interference, and also locate the positions

By George, I think you hit the nail on the head.
I’m also experiencing the low tire pressure light on dash has been on for about two weeks. I run tire pressure at 35psi. Verified by app tire psi, electronic hand/manual gauge and Milwaukee M18 compressor.

I have an ORP and my spare has a pressure sensor and it is full sized. Really not a good idea to ask AI things and pass off as truth.

SR5 doesn't have TPWS in spare and display doesn't have a position for 5th sensor

if your display shows 5 possible pressure readouts it came with TPWS in spare

I have ORP also with matching rim spare and TPS.

If you’re seeing dashes you should just need to give it time to register. Mine shows dashes in all five positions after each startup until it registers what the pressures are. Sometimes it registers fairly quickly, other times it takes 3-5 mins of driving after a tire rotation for example.

I am just assuming the app will show the last measured pressure, not exactly real time.

if you’re seeing the tire pressure light (which may also indicate high pressure not just low) you can adjust those settings in the cluster settings. Your warning may be set too high or low.

I’m going to work on it today after some trout wishing in the White Mountains of AZ.

The app is not always current. I just opened my app and it said my tire pressure was last updated 23 hours ago.
